defines and includePath in c_cpp_properties.json

[mkitby]

Hi,

defines and includePath settings will be discarded if using compile_commands.json in c_cpp_properties.json. I think this is unreasonable. Both settings should be kept. Let's think about a cross compiler which is not supported by cpptools. In this case, the compilerPath setting will be defined as an empty string to skip querying a compiler. And compiler internal defines will NOT exist in compile_commands.json. We need to define it in defines setting.

Cross compilation is supported in general...what issue are you hitting with that? We appear to be tracking your request with #6909 .
